Abstract: Siding panels and intermediate articles of their manufacture are provided. The siding panels include a central portion including an aesthetic pattern and a pair of lateral edge portions which are molded while the polymeric material is still hot or molten. One exemplary aesthetic pattern provided is a cedar shake siding pattern. Adjacent cedar shake shingle impressions have substantially the same lengths, but a plurality of bottom edges of the individual shingle impressions are beveled to give the appearance of shingles having different lengths.

Abstract: A laminated shingle is provided, having lighter and darker granule portions visible from the front, at different planes; the front-most or anterior plane generally having granules of lighter shading and the more rearward or posterior plane generally having darker granules. The darker granules in the more posterior plane are visible from the front of the shingle to provide visually sharp, precise delineation between zones of lighter and darker shading. The shingles may be of multi-layer construction with suitable adhesives securing the layers together. The darker granules may be visible from beneath the lower edge(s) of the anterior shingle, to provide a shadow line effect. Alternatively, or in addition thereto, the darker shingle zones from the more posterior plane may be visible through tab-separating slots of the lighter shaded anterior shingle portion.
